2 To all whom it may concern:

Beit known that I, JosnPr-r C. 'Psri issga native-borncitizenofi-the United States re Y sidingat .laynesville, in the county of Stearns and Statebf- Minnesota, have invented new and useful- Improvements, in Radiator-Heating Apparatus, of Which thefoliowing is a specification- This invention relates to adiator' heating apparatus, the broad object in View l3B- zingtoprovide slmple means foreflectively heating the Watercontamed inithe radiator of the circulatorywater system new commonly employed in connection with internal combustion engines, for maintaining the cylinders and other parts of the engine in comparatively cool and eilicient working condition.

Mo're specifically stated, the object of this invention-is to utilize the hot exhaust gases from an internal combustion engine mounted upon and carried by the frame of an automobile, for heating the Water in the radiator and preventing the said water from freezing, the apparatu being particularly useful in extremely cold Weather and especially Where the vehicle is allowed to remain standing for a considerable period of time.

By means of the heating apparatus herein shown and described, it is only necessary to keep the engine turning over slowly to heat the water in the radiator said Water from freezing.

A-further object of the invention is to provide apparatus of the character referred to which may be associated with the power and prevent plant of an automobile or similar vehicle either at the time of manufacture or at any time subsequent thereto. The apparatus also embodies'means by which the heating apparatus may be thrown out. of operation Whenever necessary and also to providejfor regulating the amount of exhaust gases utilized in heating the Water in tlie'radlator,

in accordance with ariations in the temperature of the atmosphere. I

With the above and other ob ects in View,

the invention consists in the novel construction, combination and arrangement of parts, herein described, illustrated and claimed.

in the accompanying drawing Figure I is a side elevation showing the radiator heating; apparatus in it applied relation to an internal combustion engine and radiator, certain parts of P motor vehicle beingjllustrated in section.

the enginecmhmiyingv usual the ordinary 7c exhaust manifold '2, exhaust 3, upper Water connection a and lower Water or "incetion 5. The construction thus far des tied and the relative arrangement of the parts mentioned, are in accordance with the present day automobile or motor velii.cle,practice,

In carrying out the present invention, I

incorporate-a heating pipe 6 iii-the hot-tom header or lower Water compartment '2' of the radiator Which compartment, as is Well. understood by those familiar with the art to which this invention appertains, communicates with the Water tubes 8 of the radi-- ator andreceives the Water therefrom the tubes 8 commiuiicating as usual with. the upper compartment or top header 9 into which the Water is conducted through the upper connection 4;. The main bod of the heating pipe 6 extends longitudinally of and Within the bottom compaitinent or header 7 and the opposite and per is of said heating pipe are d subs lly at right aiizgles to the ppe to form r ar /re dly extending" terminal. portions or 10 which extend through the Wall o the bottom. header '2 as shown in fl and suffixedly hea relation to the bottom header said heating ipe from work. can 5; a lean. n order to in nection more pipe 6 aml ploy reinforcing: c

i l each in the form of an L-shaped strip of metal of suiiicient gage or thickness to edly support the legs 10 of the heating pipe 6. The reinforcing members 14 may be soldered, brazed or otherwise permanently secured Within the bottom header 7 and it is also preferred to braze or solder the, nuts 12 and 13 in place to avoid danger of the heating pipe 7 Working loose and causing a leak, Fleirible tubular connections 15 are employed between the legs 10 of the heating pipe 6 and the feed and return pipes 11. This is done to prevent vibration of the last named pipes from being transmitted to the legs 10 which might result in causing the heating pipe and the legs 10 thereof to Work loose. i

In extremely cold weather, the Water in the radiator used in conjunction With an iii-- ternal combustion engine or a motor vehicle, frequently freezes even While the vehicle is in motion and more frequently freezes when the vehicle ,is standing still for any consid erable d ozt time. By means of the invention herein shown and described, the can ha'ust gases are utilized for the purpose oi? heating the Water in the bottom of the radiator, causing an upward trend and. circulation of the Water toward the top of the radiator as it is heated; The water thus heated in the bottom of-th radiator meets the Water heated by the engine and delivered to the top header of the radiator. It has been found. particularly important to heat the Water in the bottom of the radiator as this is a point Where the water begins to freeze.

income This is accomplished by means oi? the present invention. i vhen the machlne is standing idle, it is only necessary to run the engine "slowly as this serves to keep the Water circulating in the jackets of the engine cylinders heated and also causes a circulation of the hot exhaust gases from the engine through the heating pipe 6 and the legs or teri'ninal portions 10 thereof.

The feed pipe 11 is equipped with a regulating and cut-off valve 16, the stem of which has connected thereto an operating rod 1? which extends rearwardly through the dash or cowl 1 of the vehicle where it is provided with a suitable handle 18. This enables the operator of the machine to adjust the valve 16 so as to regulate the amount of exhaust gasespassing to the heating pipe 6 or cut the same off altogether.

ll clairn:

The combination with an internal conihustion engine, and a radiator associated therewith, of a heating'tube inclosed by and sub merged in. the bottom header of the radiator and having inlet and outlet legs extending through Wall of said header an exhaust pipe from the engine communicating With one leg of said heating tube, a stop cock con trolling said exhaust pipe, L-shaped reinforcing members fixedly mounted in said bottom header and having the legs of the heating tube inserted therethrough, and nuts threaded on said legs uponthe inner and outer sides of the Wall of said bottom header.
